Ethernet networks use a Media Access Control (MAC) address to identify and communicate with each Ethernet-based device on the network. MAC addresses are 48 bits in length. The first 24 bits represent the manufacturer of the device. The final 24 bits are a number assigned by the manufacturer so that every Ethernet device produced has a globally unique hardware MAC address. There are some cases where the MAC address of one device needs to match the address of another. You can change your MAC address on a router running DD-WRT through the administrative interface.
Step 1
Open a Web browser and then type the IP address of the router into the address bar. For example, type "192.168.0.1" and then press "Enter."
